Can you please share your backup strategies for linux? I’m curious to know what tools you use and why?How do you automate/schedule backups? Which files/folders you back up? What is your prefered hardware/cloud storage and how do you manage storage space?
What’s a backup?
I use Borg Backup, automated with a bash script that Borg provides. A cron job runs the script at the desired frequency. I keep backups on different computers, ideally I would recommend one copy in the cloud and one copy on a local machine. Borg compresses and encrypts its backups.
Edit: I migrated a server once using the backups from this system and it worked great.
I should really cron my Borg script rather than waiting for a sinking anxiety to set it and doing backups at random intetvals
Make sure to check if it actually ran from the cron job, cron is a finnicky tool
Borg backup is gold standard, with Vorta as a very nice GUI on machines that need it. Otherwise, all my other Linux machines are running in proxmox hypervisors and have container/snapshot/vm backups regularly through proxmox backup server to another machine. All the backup data is then replicated regularly, remotely via truenas scale replication tasks.
Borg via Vorta handles the hard parts: encryption, compression, deduplication, and archiving. You can mount backup snapshots like drives, without needing to expand them. It splits archives into small chunks so you can easily upload them to your cloud service of choice.
Adding my “Me too” to Vorta/Borg. I use it with Borgbase, which I like because it’s legitimately cheap and they support Borg development. As well, you can set Borg backups with Borgbase to “append only,” which prevents ransomware or other unexpected “whoopsies” from wiping out your backup history.
I backup most of my computer every hour, but have pruning rules that make sure things don’t get too out of hand. I have a second backup that backs everything up to my NAS (using Vorta, again). This is helpful for things like my downloads folder, virtual machines, or STEAM library - things I wouldn’t want to backup over the network, but on occasion I do find myself going “whoops, I wanted that.”
I also have Vorta working on my Mom’s Macbook, then have Borgbase send me an email when there isn’t any activity for longer than a couple of days. Once I got automatic pruning working right I never had to touch this again.
Borg with Vorta’s my go to as well. Resistance is futile.
Hope.
All my code and projects are on GitHub/codeberg.
All my personal info and photos are on proton drive.
If Linux shits itself (and it does often) who cares. I can have it up and running again in a fresh install in ten minutes.
But proton drive soaent have a linux client yet, I suppose you just upload your files there once through the web interface and don’t sync?
Personal stuff is mostly on my phone. And I’ll just sync to the computer what’s needed.
I plug in an external drive every so often and drag and drop parts of my home dir into it like it’s 1997. I’m not running a data center here. The boomer method is good enough and I don’t do anything important enough to warrant going all out with professional snapshot based backup solutions and stuff. And I only save personal documents, media, and custom config files. Everything else is replaceable.
yeah about the same, old coot here, I plug a USB3-SSD (encrypted with LUKS) and rsync from internal HD to this external HD. That’s it.
I do exactly this but with a little shell script that just has some
rsync -avandmv -fcalls instead of dragging and dropping.
I use rsync to incrementally back up / to a separate drive, as well as a drive on another device (my server), which then packs, compresses and encrypts the latest backup of all devices daily, and uploads them to Hetzner as well as GDrive.
Shout out to all the homies with nothing, I’m still waiting to buy a larger disk in hopes of rescuing as much data from a failing 3TB disk as I can. I got some read errors and unplugged it about 3 months ago.
I was talking with a techhead from the 80s about what he did when his tape drives failed and the folly that is keeping data alive on a system that doesn’t need to be. His foolproof backup storage is as follows.
- At Christmas buy a new hard drive. If Moore’s law allows, it should be double what you currently have
- Put your current backup hardrive into a SATA drive slot. Copy over backup into new hard drive.
- Write with a sharpie the date at which this was done on the harddrive. The new hard drive is your current backup.
- Place the now old backup into your drawer and forget about it.
- On New Years Day, load each of the drives into a SATA drive slot and fix any filesystem issues.
- Put them back into the drawer. Go to step 1.

I too am raw-dogging my Linux install
Dump configs to backup drive. Pray to the machine spirit that things don’t blow up. Only update when I remember. I’m a terrible admin for my own stuff.
Thanks to you, I don’t need to answer to OP anymore👍
etckeeper, and borg/vorta for /home
I try to be good about everything being installed in packages, even if Im the one that made the package. that means I only have to worry about backing up my local package archive. but Ive never actualy recreated a personal system from a backup, and usually end up starting from a fresh install, slowly adding back things from the backup if I missed them. this tends to cut down on cruft and no longer needed hacks and fixes. also makes for a good way to be exposed to new paradigms (desktop environments, shells, etc)
something that helps is daily notes. one file for any day Im working on my system and want to remember what a custom file, confg edit, or downloaded/created package does and why. these get saved separately and I try to remember to grep them before asking the internet
i see the benefit to snapshots, but disk space is expensive, and Im (usually) careful (enough) not to lock myself out or prevent boots. anything catastophic I have to fix is usually seen as a fun, stressful learning experience! that rarely happens anymore, for better or for worse
One reason for moving to Nix was declarative config so at least that part of my system is a series of Nix files to build into a working setup.
…The rest… let’s just say “needs improvement” & I would like to set up a NAS.
I have a synology NAS with all my documents and family photos. I’m using the synology drive app on Linux and synology photo on android.
All of that is backed up on Backblaze
Currently I use Borg Backup with Vorta as a GUI. I don’t really do anything automated/scheduled, I just back it up manually to an external SSD every few days or so. I pretty much do my whole
/homefolder, except for a couple of subfolders that aren’t really necessary (andVideos, which I back up separately.)I do eventually want to upgrade to a NAS, but I’m waiting until we move to start setting that up. Also I don’t really have an off-site plan yet which I know is bad, but I need to figure that out.
